MPB 44 M master controller<br />
Universal traffic light system for flexible control of up to maximum<br />
12 signal groups, for example at pedestrian crossings with request<br />
function as well as vehicle-actuated alternating one-way traffic,<br />
T-junction or crossroads situations, possibly with additional turning<br />
lane, blinking light or waiting signal. The MPB 44 M/S series is based<br />
on the outstandingly proven MPB 4400 system which has been<br />
popular for many years. Operation is also the same so that no relearning<br />
is necessary. Depending on the technical features, already<br />
existing MPB 4400 traffic lights can be simply integrated in the new<br />
system.<br />
The MPB 44 M controller is equipped as follows:<br />
• central emergency-off switch for the complete traffic light system<br />
• residual current-operated device (RCD switch)<br />
• digital AC metre showing the 230 V energy consumption<br />
• 230 / 42 V transformer for central power supply to all signal heads<br />
directly from the controller via the data cable<br />
• programming of up to 4 groups directly in the controller via the display<br />
• selection switch for immediate manual traffic light control for<br />
manual mode, blinking lamp, lamps off and continuous red<br />
• programming interface for 12 signal groups (laptop connection)<br />
• connection for an external printer or laptop (USB and serial)<br />
• freely accessible 230 V service power socket<br />
• connection for parallel signal head and SMS messaging module<br />
• synchronous input for coordination of progressive signalling<br />
• automatic mains / battery changeover for 12 V battery operation<br />
• MPB 44 S control PCB for the first carriageway signal head<br />

MPB 44 S slave signal head<br />
equipped in each case with its own MPB 44 control PCB that also<br />
covers the connected additional equipment and communicates with<br />
the central MPB 44 master controller via one cable for databus and<br />
42 V power supply. All signal heads are equipped with LED technology<br />
and a 42 V AC/12 V DC power supply unit. There is also a connection<br />
for 12 V power supply with automatic changeover for possible battery<br />
operation of the signal head. All carriageway signal heads are<br />
prepared for directional radar detectors for vehicle-actuated traffic<br />
light control or for our PB-CAM as video detector for registering<br />
traffic volumes. There is also an output for a parallel signal. A request<br />
traffic light for pedestrians is provided by plugging request buttons<br />
directly into the signal head without needing additional wiring from<br />
the button to the controller (holder included in the scope of supply).<br />

Just one single cable is needed to operate the MPB 44 system.<br />
Just one cable is now responsible for data transfer between master controller and the individual slave signal heads in<br />
up to 12 groups together with the central 42 V power supply from the controller, thus clearly minimising the wiring workload<br />
on site (see diagram). No extra cables are needed for power supply, detectors, buttons and data bus so that this one-cable<br />
solution saves lots of time and costs in installing and dismantling the traffic light systems.<br />
